transfering compositing nodes with render layer nodes
Append a Scene
Compositor nodes belong to the Scene settings.
You just have to Append a Scene from a blendile containing the compositor setup you want. Go under -&gt; File -&gt; Append, pick the file and look under the Scene folder.

Then go to the scene selector, open the compositor in the appended one and copy past the nodes in yours.

Remember to update the render layer input scene in the copied compositor node setup.
